To all whom it may concern:

Be it known that we, Ronnn'r ALKAN and GEoRGnsLnsoURn, citizens of theFrench Republic, both residing at Paris, France, have invented certainnew and useful Improvements 'in a IIooking Ring for a Mass Suspended toReleasing Devices, of which the following is a specification.

This invention relates to a ring or loop allowing to suspend a mass to areleasing device with automatic hooking and arranged in such a manner asto allow the use of a simple lifting apparatus to secure the .hooking orhanging of the mass to the releasing device.

This ring which may be used for instance with projectiles, mail bags andthe like thrown from airshlps 1s characterlzed by the presence of threeeyes: one for the pas sage of the suspension hook, onefor the attachmentof the mass, one for the attachment to the lifting gear, these threeeyes being arrangedin such a manner that, when the mass is suspended tothe lifting gear, the eye for the attachment to the mass takes aposition which is vertical in relation to the former one, while the eyeof the sus pension hook is located at a certain distance from thisvertical line in such a position that the mere lifting or hoisting ofthe mass or body brings the eye adapted to be attached to the suspensionhook .to such a suitable position relatively to the suspension hookforming partof a releasing device of a known system and of such formthat the passage for the hoisting rope is left entirely free.

When the ring is hooked and when it is possible to slacken the liftingcable, the ring is slightly shifted and the point of fastening orattachment to the mass places itself vertically to the contact pointbetween the ring and the hook.

A form of construction of this ring is shown by way of example in theaccompanying drawing in which: I

Fig. l is a perspective view of the ring.

Fig. 2 is a side view thereof partly in section.

Fig. 3 shows the ring in the position of rest.

Fig. 4 shows, on a smaller scale,the ring in the hoisting position.

Fig. 5 shows the ring when hooked.

In this drawing, 1 is the eye for the hooking of the ring and2 isthe eyewhich is used for attaching the lifting gear 8, the

hoop 8 ofwhich passes through the slot I and is engaged into the shaft6. This shaft 6 which is put in position for the hoisting operation andwhlch is removed after the mass has been hooked or fastened, is steadiedduring the hoisting operation through wedging between the faces a and Z)on the one hand and the face 00f the lifting loop on the other hand.This shaft 6 can more over be stopped through the medium of a shoulderor projection 6 of the free end or by means of a pin or a safety pinwhich 4, the ring is in balance between two equal and opposite powers:1st, the weight of the I load P exerted upon the fastening point m ofthe mass; 2d, the lifting strain H exerted upon the fastening point nof'the cable 8. In this position, the hooking or fastening eye 1 isthrown beyond the vertical of the suspension point and comes into thesuitably arranged hook C of the releasing device. The upper edge of thering pushingthe upper face. of the hook opening causing the revolutionand the closure of the throwing in device.

The ring is then fastened. lVhen the cable or rope 8 is slackened (Fig.5), the ring assumes such a position that the point on, at which thisring is secured to the mass takes under the action of weight a verticalposition relatively to the booking or fastening point 0.

The loop of cable 8 can then be unhooked and the body or mass 9 remainssimply suspended to the hook of the releasing de- According to the abovedescribed arrangements the ring shows the following features:

1. The ring can be turned down over the mass in the position of rest.

2. In the hoisting position, the eye securing the attachment orfastening to the suspensionhook of the releasing device is reInOVediEflOHl the hoisting line.

3. the position of fastening to the revice.

leasing device, the eye for attaching the hoisting cable is removed fromthe vertical of the suspension point.

lVe claim A suspension ring for a mass or body adapted to be secured toa releasing device, characterized by the fact that it comprises,

in combination, an eye for fastening the mass to be suspended, then,thereabove, an eye for the purpose of fastening to a lifting or hoistinggear, and further above, an eye for the attachment to the releasinggear,
